This is amazing. I love the retro-cubical feel it has. Good use of colors. The only slight problem you have is your lighting. You drew a light reflecting on everybody but yet you have no evidence of a light source. I think you should add a Sun in the background to show the light source. The characters on the right side seem to be a little bit dark compared to the ones on the left Also the background behind them is a little blank maybe add a sky. Other Than that everything seems great!

You don't have to incorporate these things if you don't want to, it's just my opinion!

This is an excellent piece of artwork, give yourself a pat on the back!

Thanks my friend. I guess I have to ask u for more patience. I am working hard to finalaze the book, but first in german language. Since the the Book contains a lot of text it wont be easy to translate it . But ther will be a english version as soon as possible, mos def. Stay tuned
